UNITED. STATES PATENT oEFIoE.

WILLIAM R. Fox; or GRAND RAPIDS, moment; TYPE-BAR 'AND HANGER AND METHOD OFOONSTRUOTING SAME.

To all whom it may concern.-

. zen of the United States residing at Grand in Letters Rapids,in the county of Kenn-State of Michigan, have invented certain new and useful Im rovements in Type-Bars and Hangers and Method of Constructing the Same, of which the following is a specification.

This invention relates to an improved type-bar hanger for typewn'ting machines and the method and means of constructing the same. It relates more particularly to an improved method and means ofmanufacturing the im roved type-bar hanger described fatent No. 656,785, August 28th, 1900, to Fox et al. v

The objects of this invention are to produce a type-bar hanger in which theparts shall be a closefit when the t e is thrown to the printing point, and sha have a free movementwhen the type is at rest in the basket. I

Further objects relate to the details of the manipulation of the hanger in conjunction with the pivot of the type-bar, and the pro or formation'of the same.

bjects relating to details will definitely iippear from the detailed description to fol- I accomplish the objects of my invention by-the devices and means described in the following specification,

The invention is clearly defined and pointed out in the claims.

My improved typebar and hanger and structures for carrying out my improved method iii the process of construction are a clearly illustrated in the accom anying drawing forming a part of this speci in which:

and Fig. 12 is an enlarged detail view 0 the completed type-bar and hanger, the adjusting screw merely being omitted.

In the drawing, the sectional views are takenlooking in the direction of the. little arrows at the ends of the section lines, and

similar letters of reference refer to similar parts throughoutthe several views. I

Referring to the lettered parts of the drawing: The press A is provided with a suitable lever A for acting upon the hanger B. A-

die-plate A is placed on top of the press, and

a plunger bar a,. carrying pivot-like(projec' tions 0/ a at each side of the upper en thereof, is-provided, which upperv end extends up I through the top of the d1e-' late A. A recess is formed across the p ate A" which is curved downwardly at the central part (see details in Fig. 8) into which the han er B is forced by the pressure on the lever A. An

adjustable stop a. limits the'movement of.

the'lever A to prevent folding the blank too far at this stage of the manufacture.

The hanger blank B is punched from sheet metal, as indicated in Fig. 6, and a recess b is cut into each side to rcceivethe pivot pin of the typebar when the said hanger is folded. The blank as illustrated in Fig. 7 is inserted into the die-appearing in Fig. 1, the same be moval of the pivot in a. The hanger is ,then placed around t e pivot c c of the typebar, and the operation is completed in the press D which is especially adapted and de-.

signed for that purpose. 4 A dielate D is provided, which is of such co guration that the folded hanger can ing put down over the pivot pins 0, a longiat a very acute angle to permit their adjustment byv a proper set screw. The dieplate'D is slotted to permit the de ression of the type-bar into the same, but t e sides are conformed to engage and fold the typebar hanger. I

On to of the die-plate D are oppositely arrange plates D D.which serve to guide and properly locate the hanger. between them in the operation of folding. In these plates D D are oppositely'arranged pins E E with suitable buttons on their outer ends for manipulating the same, the pin E being Withdrawn by a spring e. The pin E is shorter than the pin E and a pin e is provided in the samerecess, the same being'of a iengthsubstantially the same as thewidth of the hanger so that it canbe depressed through the o ening in the die-plate E.

Wfien the hanger is artially folded it is then placed on the type 'ar and thetypebar and its hanger are brought'into position, as indicated by dotted lines inFig. 5. The slot C in the typebar for the key-leverconnection is then brought op osite the pin e and the coupling (1 from the ever D of the press is bifurcated and raised up toemb'race the short end of the lever of the typebar. The pin e is then pushed through and couples the plunger d to the typebar. The lever D is then depressed and, owing to the fact that pin 6, the typebar hanger is drawn down into the die-and in this way the metal of the hanger is folded tightly around the pivot of the typebar, the movements of the lever being continued until it comes into contact with the stop F which-is adjustable tothe 5 "'SCTGW. The hanger is folded onto the ty epivots c on the typebar pe rightposition for properly closing and folding .the opposite sides of the typebar hanger together. The art is then raised up, the pin e forced out 0 its connection by the pin E being forced into the same, which carries the pjinlE back and the spring 6 returns the in to its proper-position, when the type 'ar with its hanger can be lifted and raised from the die. and will .be ready to receive its setbar pivot bythis means. By this metho it Will also be noted that thehanger is folded onto the typebar pivot whenv the typebar is in a osition of rest or in its initial position in the an er. This is of great advantage becauseof the great difficult,

E ctly; and it will e noted that ifthere are any slight im 6%- fections in the pivot that the pivot wil fit more closel in its bearingwhen the ty ebar is moved om .the position in which the hanger is' formed onto-the same-so that by .this method, the typebar will be perfectly t an will come toa. tight. fit

free in the baslre stantially the plunger is coupled to the typebar by the with. laterally extending offorming the at the printing oint, the tightness of the fit being very readl y regulated by the set-screw of the hearing, The hanger may be wrapped around the pivot by holding the pivot against the recess 1), then folding the hanger around the pivot. The first operation of bending, as shown in Fig. 8, maybe omitted entirely and. the bar .and pivot used to bend the blank'from the form'show-n in Fig. -7 to that of B inFig. 11 The first o eration is ordi-' narily of advantage. It willlbe seen, therefore, that. by this method of forming the typeveryfree pivotal movement of the same with a veryv close joint. at the printing oint, and yet the closeness of the fit of t e joint can be regulated so that the movement is, for all practical purposes, perfect. Also, by

this method, it is possible to manufacture the typebar hanger by wrapping the soft steel hanger around the-hardenedpivot and thereby securing a perfect fit of theparts,'which .has beenfound impossible to accomplish by machining operations because on such very. small articles, where the'conical fit'is desired, it is a matter of the greatest difficulty bar and hanger a result is secured of having to get ,a bearing forthe ivotv that will exactlyi conform,.or to finis the pivot so perfectly-that it will exactly fitv the bearing; whereas, by my method herein set forth, suberfect pivoting of the typebar can be secure with great ease and rapidity, and the 'slight irregularity of the pivot pin which is almost unavoidable is utilized in securing the very free pivoting of the typebar while in motion and a snug fit of the same at the printing point, advantages which will appeal to anyone familiar with the manufacture of typewriters. I

Having thus described my invention, what I claim as new and desire ters Patent is;

1. The combination With-a type bar G with laterally extending pivots therefor, of a hanger folded about and conformed to. the

said pivots and adapted to beadjusted rro thereon, the same being folded and conformed onto the pivots, with the typebar arranged at the angle of the position of rest, whereby irregularities ofithe .pivot are impressed into the bearing and are utilized for securing a tight jointtat the-printing point .and a free pivoting at other'points, as specified.
